LOCOMOTIVE' ARCH AND BRICK THEREFOR.

Application filed. June 1,

T0 all'whom z't/mag concern:

Be it known that I, RALEIGH J. HIMMEL- RIGHT, a citizen of the United States, residing at Englewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Locomotive Arches and Bricks Therefor, of which the following is a specification.

This invention relates to locomotive fire box arches and to bricks therefor, and particularly to that type of arch which has become known in the art as the sectional arch.

Its principal object resides in the provision of an arch composed of a plurality of bricks of a single pattern which can be assembled in alternate reversed relation to provide gas mixing pockets on the under surface of the arch. It is also an object of the invention to accomplish the foregoing by means of comparatively thin arch units or bricks which can be arranged either singly or in groups. A further object of the invention is to provide a brick unit for the construction of locomotive fire box arches which is socketed approximately at the middle of one end in order to embrace the tube for approximately onehalf its circumference and which is socketed at the other end at the lower corner so that this corner may rest upon the top surface of a tube.

These, together with such other objects as may hereinafter appear, or are incident to my invention, I attain by means of a construction which is illustrated in preferred form in the accompanying drawings, wherein:

Fig. 1 is a partial vertical transverse sectional view through a locomotive fire box illustrating an arch applied therein which is composed of my improved bricks; Fig. 2 is a transverse sectional view on an enlarged scale through the supporting tubes illus trating more in detail the manner in which the bricks are applied; Fig. 3 is a plan View of the under face of the arch in which my improved brick units are arranged in one of a number of possible ways; and Fig. 4 is a plan view of the under surface of an arch with the brick units arranged in another way.

The fire box illustrated is of usual construction and includes side sheets 1, a crown sheet 2 and a plurality (in this case four) 1922. Serial No. 565,076.

of arch-supporting which are arranged to extend rearwardly and upwardly in the fire box in the manner well known in the art. The view as seen in Fig. l is taken from a point at the forward end of the box looking towardthe rear.

The arch, as is usual in this construction, comprises the middle spans A between the tubes and the side spans B between the outermost tubes and the side sheets. The spans A comprise the main body or middle portion of the arch, as it is termed, and the spans B comprise the side or wing portions of the arch.

The individual units 4 entering into the construction of the arch may be described as being of a general arcuate shape with, however, the depth at one end considerably greater than the depth at the other. I have referred to the deep end with the reference character 5 and to the less deep end with the reference character 6. The deep end is socketed approximately in the center and is adapted to embrace approximately onehalf the circumference of a tube, while the shallow end is socketed at the lower corner and is adapted to rest upon an upper onequarter of the surface of a tube. By virtue of the projecting portion 7 at the thick end of the brick it is possible, when the bricks are assembled in alternated reverse relation, to form pockets on the under face of the arch, as clearly disclosed in the figures of the drawing.

The arch may be constructed of a plurality of single units arranged in alternate reversed relation, as indicated in Fig. 4, or it may be composed of a plurality of larger bricks, each of which includes a number of smaller units arranged in the same direction as indicated in Fig. 3.

The side spans B are composed of a plu-.

rality of bricks adapted to rest upon the tubes at their inner ends and to lean against the side sheets 1 at the outer end.

What I claim is:

1. A sectional arch for a locomotive fire box including in combination with spaced supports a plurality of reversible brick units, each of which is constructed to project below the plane of the supports at one end and to rest upon the supports at the other end so that when the bricks of an arch circulation tubes, 3.

are arranged in alternation end for end a plurality of pockets will be formed on the under face of the arch. V

2. An arch brick for tube supported arches constructed with one end having a socket adapted to engage the tube above and below the center line thereof and the opposite end adapted to rest upon a tube whereby, when a plurality of said bricks are assembled in alternately reversed relation, an arch may be produced with a plurality of pockets in a face thereof.

3. An arch brick for tube 7 supported arches constructed with a thick end having a socket adapted to engage the tube above and below the center line thereof and a thin end adapted to rest upon a tube whereby, when a plurality of said bricks are assenr bled in alternately reversed relation, an arch may be produced with a plurality of pockets in a face thereof.

In testimony whereof, I have hereunto signed my name.

RALEIGH J. HIMMELRIGHT.
